Drill drivers

The DDH181X drill driver from Bosch Power Tools features Active Response Technology, which allows contractors to tackle high-torque applications while reducing the risk of kickback. An integrated acceleration sensor limits the tool’s rotation by detecting sudden movements and cuts off motor current. The DDH181X is compatible with all Bosch 18V Lithium-Ion batteries, weighs five pounds or less, and measures less than nine in. in length. www.boschtools.com
